.5 A further object is a drum in which provision is made for guardingagainst tampering with the pump mounting. n

A still further object .toprovi'defor facility in attaching anddetaching the pump.

50 n A- still further object is to provide a drum which is simple indesign and which may be manufactured economically. r. l f

The invention is illustrated in the accompanying drawing in whichi 5Figure 11 is a perspective view of a drum embodying the features of theinvention;

Figure 3 is a fragmentary View taken along line 3-3 ofFigure 2; n '1 lFigure 4 is a fragmentarysection taken along .lined-4 of Figure 3; I j'Figure 5 is a sectionalview of amodifled :form of valve for admittingair to the drum; and 1,5 '/Figure 6 is an enlarged detail section takenalong'line 6--6 ofv Figure 3.x I The drum, asillustrated, includes aheadl 6 which is formed with openingsl and 8 (Figure y 2), the metalsurroundingsaid openings being extruded toA providenecks` 9 and I U,respectively. The opening I is .closed by a cap IVI while the opening 8is closed by a similar cap I2. Thel said caps carry sealing elements I3which seatf upon lianges I4 formed on the necks l9 andlll and arepreferably scored `as indicated at I ;4 (Figure 3) in order tofacilitate theirl removal; The opening 1 communicates with the,interiorA 1' of the drum through' a tube I6, the upp-erend of which issuitably secured to the under side ofof the head 6 and the lower end ofwhich is4v formed vwith a port I1. A valve I8 cooperates" with the saidport. VIt is normally partially open and is, therefore, adapted topermit air to enterl the drum or the contents to be drawn off when 5,theca p II is removed. AThe saidl valve will;l

f the frictional vengagement between the arms 25 close,;however, in theevent that an attempt is made torefill the drum throughV the opening 'I,

an apertured plate I8a which is secured inthe tube I6 preventingtampering with the valve.

- The opening 8Jis adapted to accommodate the 5A barrel ,.I9a; of vthepump,l which is employed to draw olf the contents of the drum. Inaccordance with the invention an internally threaded element is arrangedunder the opening 8 in a shallow depression 2| which `is formed in the10 head 6 and is supported therein by diametrically opposed holders 22,a hard metal ring `20a preferably being secured inthe depressionbetweeny the top of the vhead and/the said ele- 'ment -The lholders 22,as illustrated, are se- 15.;

cured by rivets 22a in end-for-end relation to 'the under side rof thehead 6 and are formed `with arcuate, offset, resilient tongues 23 and`depending tail-pieces 24." `The outer ends of the 1 tongues 23 are'formed with openings 23a 20 through which pins 23h extend.V The latterare headed; they are carried by the head 6; and they permit freemovement of the said tongues 'toward thefhead but prevent their movementin vthe opposite direction'beyond the dotted line po- 25 sitionindicated in Figures 2 and 5. 'I'he tongues 23, `cooperate with arms 25which are formed yor provided upon the-element 20 and preferably areinclined slightly, toward ythe drum head, their off-settingprovidingshoulders 26 against which 30 vthe said armsabutl` Preferably ahard metal ringV 23C is secured to the head 6 around the depressionfZI,the inside diameter of the said ring being substantiallytthe same asthat of the depression 2| while the loutermarginal edge over- 35 liesthe arms 25.

`,The element 20 is lapplied to the drum head by initially adjustingitso that the arms 25 are located in the spaces between the ends oftheholders 22. It is then free to enter the depression 2 I.,y Thereafterthe outerends of the tongues 2k3 arel sprung away from the drum head andtheelement rotated in a counter-clockwise direction to cause the arms 25thereof to move behind the tongues into engagement with the shoulders26, it being noted that the pins 23h are located just beyond the path ofthe arms 25and hence do not interfere with the manipulation of the saidelement in the manner described. The element will b'e held in theposition described byV and rthe tongues 23.

The pumpwhich is employedV to draw olf the contents `of the `drum isattached (after removal of the cap'l2? inserting thebarrel Isa there-55C of through the opening 8, the said barrel passing through theelement 20 until a'threaded section 29 thereof engages the threads inthe element. When the parts are so adjusted a rotary movement of thebarrel l9a in a clockwise direction will cause the pump to be firmlysecured upon the seat provided by the flange of the neck I0, rotation ofthe element 20 with the barrel being prevented by the engagement of thearms 25 with the shoulders 26. The contents of the drum.y may,therefore, be drawn off as desired. When the drum has been` emptied thepump' may be removed by rotating the barrel Illav in a counterclockwisedirection. The element 20 turns with the barrel lila until it isarrested by the engagement of the arms 25 with the tail-pieces 24, asillustrated in dotted lines in Figure 3, the said arms forcing thetongues 23 aside and passing beyond their outer ends before engaging thetailpieces. Continued rotation of the barrel l9a, therefore, unscrewsthe element 20, it being noted that the tail-pieces 24 are of such alength that they hold the element against rotation while permitting itto move toward the lower end of the barrel as it is unscrewedfjUpondisengagement of the threads in the' element With those on the barrelthe element slides down the barrel and drops into the' bottom oi thedrum.

A modified form of valve for venting the drum isshown in Figure 5. Inthis embodiment an internally threaded plug St is secured in the openingl, The said plug carries a' threaded element 3l which has heads .im and3io and which is adjustable between the limits yindicated in dottedlines; it is formed with acentral bore 32 which connects with a lateralpassage 33; and it is adjustable to one position in which the head tiaseatsl against the plug to seal the opening l and it is adjustable to asecond position in which the head Sia is spaced from the end of saidplug to permit air to enter the drum through thepassage 33 and the bore32.

From the foregoing -it will be apparent that the pump can be atta'chedto the drum only once, its removal automatically dislocating the element2li so that itis unavailable for further Not only is refilling of thedrum thus vdiscouraged but kprovision is made "for 4guarding againsttampering with the pumpy mounting, the

rings 2da. and 23o cooperating to provide a shield which is hardenoughto resist the action of a drill or similar tool. Unauthorizedaccess to the element 2B, after the pump is 'once attached, for thepurpose of locking the said element so that it cannot turn with the pumpwhenthe latterV is removed is thus prevented. At the same time the pins23h make it diicult to insert a tool through the openings (after thepump has been removed and the `element 20 has dropped into the bottomofthe drum) and bend the tongues 23 downwardly so' that the element 20may be` ing la dispensing pump to a container having an opening throughwhich the barrel of the pump is adapted torbe inserted,l said meansincluding an element which is located Within said container and meansfor supporting said element in such relation to said opening that it isengaged byv a part on said barrel when the latter is inserted throughsaid opening-and moved in one direction, said last named means beingoperative to release said element when said 'barrel is moved in a seconddirection so that when it is disengaged from said part it will move to aposition in said container in which it is rendered ineffective forfurther use. o
